#2 – Chris Jericho
There's has never been, and likely never will be, a WWE Superstar quite like Chris Jericho. He holds virtually every record that has to do with the Elimination Chamber match, and nobody is even close to catching him.
In 2002, Chris Jericho competed in the first ever Elimination Chamber match, lasting 30 minutes and eliminating both Booker T and Kane. In 2003 he wrestled for 16 minutes, eliminating Kevin Nash. In 2005 Jericho lasted almost 28 minutes, eliminating Edge. After taking some time away from the wrestling world, he returned in 2008, entering from the first position again and going 20 minutes to eliminate both JBL and Umaga. 2009 saw another 24 minutes and a pin on Mike Knox, before Edge eliminated him. 2010 was Chris Jericho second trifecta, and his first Elimination Chamber win! He wrestled for 25 minutes, actually pinning the Undertaker (with some help from Shawn Michaels) and became the new World Heavyweight Champion in the process.
Somehow, we're not done yet. Jericho returned to the Chamber in 2012, eliminating both Dolph Ziggler and Kofi Kingston in just 8 minutes, before CM Punk kicked him in the side of the head and knocked him out of the match. This marked the first time somebody in the Chamber, who was in the match when the bell rung, was removed from the match without elimination. In 2013, Jericho's last Elimination Chamber match, he lasted over half an hour.
Let's run down those statistics one more time. He has entered from the brutal #1 or #2 spot 5 times. He's competed in 8 elimination chamber matches, scored 10 eliminations over 10 different people, is one of only two people to wrestle in three back-to-back Chamber matches twice, was never actually eliminated in 2012, became a World Heavyweight Champion by defeating the Undertaker, and has spent almost three hours inside the structure. The first ever Undisputed Champion may just be the Undisputed king of the Elimination Chamber – except there's one "king" who's done it just a little bit better…
